----------------------------------------
Summary: Flink SQL Planner Module doesn't read config from
flink-conf.yaml
Key: FLINK-29333
URL: https://issues.apache.org/jira/browse/FLINK-29333
Project: Flink
Issue Type: Bug
Components: Table SQL / Planner
Affects Versions: 1.15.0
Reporter: Dhananjay Badaya
PlannerModule class doesn't seem to be reading the configs from the
{{/etc/flink/conf/flink-conf.yaml}} directory. ([code
ref|https://github.com/apache/flink/blob/master/flink-table/flink-table-planner-loader/src/main/java/org/apache/flink/table/planner/loader/PlannerModule.java#L95]).
It is only reading the default config values defined in the Java code. So, we
can't override configs using flink-conf.yaml.
Use-case: We need to modify the default value of {{io.tmp.dirs}} as the default
value (/tmp) is a symlink on our platform , and
{{java.nio.file.Files.createDirectory}} (which is used By Flink in this case)
doesn't handle symlinks properly
[ref|https://bugs.openjdk.org/browse/JDK-8130464].
